Pretty Schnazzy: realdice dot com (sorry, can't post a URL yet) - Costs $8 per month for online access to Backgammon, Hold 'Em, Chess, Sudoku, Mahjong and Dominoes, or you can buy each individual "offline" game OTA for around $15 one-time. The interface is beautiful and graphics heavy, but the individual games are memory hogs, the menus are sluggish (even offline), the AI plays poker like a wuss (very rarely bets, calls or raises you), which makes it fairly boring, and there are not enough people online yet to make the online play worth it. It's cross platform and international, meaning you can be on your BB in NYC playing against a Treo in Japan.
